Display
 |
The measuring devices are equipped with a back-lighted, 2*8 character dot-matrix
LCD which can display one measured value together with its corresponding physical
unit at a time. It is also used for displaying setup and other informations.
|
The VSM-02 measures several values at the same time (the
standardized volume flow, the line overpressure, the temperature, density
and so on). All results can be displayed using the function keys at the
measuring device. The tables below show all possible displays of the
different device models.
Besides the displays in
standard mode there are also several
displays and input possibilities in
setup mode, which is activated if the device is
switched on while holding down the white key.
In setup mode the VSM-02 can be fitted to
virtually all media and measuring tasks by
entering the medium's physical characteristics.
So there is no restriction to the preselected media already stored in the VSM-02.
On our service pages you will find
tables with characteristical constants
for many other gases and liquids, which are of technical or medical importance.

These displays are directly available at the VSM-02. In combination
with the included software it is
possible to read out and display additional measured values (e.g. the
measured density). In general the software offers all means for remote
query and control of the measuring device and thereby widens the scope of
possible uses for the VSM-02.
